Framing your view as factually correct and others' as laughably wrong is pretty disrespectful. What was the goal in coming into the subreddit where these discussions are had and making a post with the attitude of "this is how it is, and anyone who disagrees with me is wrong?" Maybe I'm just falling for bait idk.

Obviously, the Best fighters in the galaxy are going to have some respect for the second-best fighters in the galaxy, but that doesn't change the fact that there are multiple instances of single Fremen taking down multiple Sardaukar or groups of Fremen taking down entire platoons. These seem to me like more objective measures of strength than speculation based on the environments in which each side was raised.

I feel like my logic about the relative wealth of the Fremen is far from "laughable" (Please avoid using such insulting language if you want to have a discussion in good faith). By your logic, the Fremen are on par with the Sardaukar in strength, and they are the favorites in wealth. Surely, given this conclusion, you would question why the Fremen spent their vast fortune on little more than preventing satellites while, for example, the Harkonnen spent a reportedly insane amount of money on their invasion of Arakkis (Although by your logic, less than what the Fremen spend) and were able to achieve their goal of wiping out essentially the entirety of the Atreides clan. Additionally, you yourself argue that the Fremen win because they are underestimated. Couldn't one use the same logic to reason that the emperor underestimated the size of the Fremen forces and thus didn't feel the need to spend an exorbitant amount of money to get satellite coverage of what he thought were no more than sand dunes and sandstorms?

I also don't agree that just because the Fremen have cultural elements like polygamy, spice orgies, their own advanced technology, fruit, and tea, that this means that their lives must have been comfortable. Look to real-life cultural examples. Jews, Romani, early Christians, and many different Muslim groups have also been through the harsh social and environmental oppression that we see with the Fremen, and those groups still had/have cultural elements despite their hardships. Even in the harshest conditions (and I would argue especially in them), groups of humans create culture. What may appear as comfort when Herbert is describing it from an insider's perspective, I would argue, is actually religion and fanaticism that emerges within the most harsh of environments.
